----------- Adoption of the Standard
The American National Standards Institute (ANSI) approved DES as a private-sector standard in 1981 (ANSI X3.92) . They called it the Data Encryption Algorithm (DEA). ANSI published a standard for DEA modes of operation (ANSI X3.106) , similar to the NBS document, and a standard for network encryption that uses DES (ANSI X3.105) . Two other groups within ANSI, representing retail and wholesale banking, developed DES-based standards. Retail banking involves transactions between financial institutions and private individuals, and wholesale banking involves transactions between financial institutions. ANSI’s Financial Institution Retail Security Working Group developed a standard for the management and security of PINs (ANSI X9.8)  and another DES-based standard for the authentication of retail financial messages (ANSI X9.19) . The group has a draft standard for secure key distribution (ANSI X9.24) . ANSI’s Financial Institution Wholesale Security Working Group developed its own set of standards for message authentication (ANSI X9.9) , key management (ANSI X9.17) [55,1151], encryption (ANSI X9.23) , and secure personal and node authentication (ANSI X9.26) . The American Bankers Association develops voluntary standards for the financial industry. They published a standard recommending DES for encryption , and another standard for managing cryptographic keys . Before the Computer Security Act of 1987, the General Services Administration (GSA) was responsible for developing federal telecommunications standards. Since then, that responsibility transferred to NIST. The GSA published three standards that used DES: two for general security and interoperability requirements (Federal Standard 1026  and Federal Standard 1027 ), and one for Group 3 facsimile equipment (Federal Standard 1028) . The Department of the Treasury wrote policy directives requiring that all electronic-funds transfer messages be authenticated with DES [468,470]. They also wrot...
